To all whom it may concern:

Be it known that I, Lo DAVE m, a

'- citizen of the United States residing at A further object of the invention is to save the labor cost of the setting gang and transfer men, by setting the product in the chambers of the kiln; said product being transferred direct from the machine rooms by means of ofl-bearing-belts, made to enter the kiln.

A further object of the invention is to i save the cost of fuel in drying and burning the product, by means of tunnels and ducts,

properly constructed, and operated by suc-.

tlon and circulating fans, governed by suitable dampers, so arranged that all. waste heat is conserved from the, burning and 'cooling sections of the kiln, being transferred to "the other sections and utilized in drying the green product inits turn.

' forth and then A still further object of theinvention is tosave from three to six da s in burning the product over the ordinary orm of kilns, due to the fact that when the product has been properly dried by waste heat, it bein then heated through, is ready for raising t e fire to a higher degree of heat.

A still further object of the invention is to make possible the removal of the burnt product from the sections, sooner than in the kilns of ordinary construction, from the fact that the heat is drawn from the cooling section and utilized in other sections.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set specifically designated by the claims.

In order that those skilled in the art to and the end wall 25.

g a part of this specification, in whichgure 1, is a front elevation of the apparatus. Fig. 2, is a side elevation. Fig. 3,

is a plane view. Fig. 4, is an enlarged side elevation. Fig. 5, is an enlarged section on the line C-C of Fig. 4. Fig. 6, is an enlarged section on the line EE of Fig. 5. Fig. 7, is an enlarged section of the line F-PF of Fig.5. Fig. 8, is a section'on' the line DD of Fig. 4. Fig. 9,.is a section on the line B-B of Fig. 5; and Fig. 10, is a section on the line A--A of Fig. 5.

In carrying out my invention as here embodied, 1 represents the kiln proper. In Fig. 1, two of these areshown side by side, having a passage way 2 between, them and the passages 3 and 4 on either Tunnel ways 5, 6 and 7 extend backward and are connected with a cross-tunnel way .8, to

which is attached a suction fan 9. A circulating fan 10 is connected through the main cross pipe 11, having various branches 12, which connect with continuous tubes 13, which extend along the top of the kilns in the same direction as the tunnels 5, 6 and 7. The discharge from the fan 10 is connected with a cross pipe 14 and this in turn by branches 15 with another set of continuous tubes 16 running arallel with'the tubes 13. The tubes 13 are connected by branches 17 with the vertical ducts 18, each of these branches being provided with a damper 19 and in like manner the tubes 16 are connected by branches 20 with the vertical ducts 18 and controlled by dampers 21. The tubes 13 have dampers placed at 22, and the tubes 16 dampers placed at 23.

In the side elevation, Fig. 2, two sections of kilns are shown and part of a third being broken 'ofi'. These are divided by walls 24 A number of arches 26 are shown having grate bars or burners 27 permanently set therein, and an arch way 28 also through which the section of the kiln is charged and discharged, the temporary brick wall 29 being put in after each charge, thus formin the entranceto each section of the kilns he grate bars and bag wall of the charging and discharging arch- .ways 28 are to be, removed and replaced at every discharge and charge of the kilns as is customary. The kilns are designated as =X-, Y-and'Z. 30 pass from openings shown at 35 and connect with those portions- 31 the side walls ofsection-X and then pass through all of the sections, and have dampers 32 located adjacent each partition or wallv 24, kept'closed in regular usage, but,

of the ductsv 3O situated within section Y,

and the ducts under sectionY are desig-v nated by the numeral 38, and said ducts are in the same line with the ducts 34 of section X, and like said ducts 34 rise as at 39 and connect with those portionsof the ducts situated within section Z. .The risers 35 and 39' are each provided with ,a baflie plate 37 and 41 respectively, adapted to control the Fig. 9 is a section under. the floor-of the section X. The vertical ducts 18 are here connected with horizontal ducts. 34, and g these in turn connect thejpassages 42, ands 44,.forming a net work of passages, and-the? V "o f the ducts. are also closed, So-Jthatthehot brick work of the' floor 'ofqeach section is i of the kiln land the assages 44, this has ' and the'grate bars 27, which end in thebag' made open as at and} work,-so that there shall be a'more or .less

restricted passage waybetween the interior shown more fully in ig. 10.

Fig. 10 being a section abovethe floor of the kiln shows the vertical ducts 18 passing through the solid brickwork, the arches 26 walls 46, where the heat from the fire is thrown 'up into the arch of the kilnl, and

.this occurs in each" of the sections. In the tunnel ways 5, 6 and. 7 are openings as at 47 having covers 48, which covers can be re moved and portable goose necks 49 substi-. tuted as later described. Where the tubes 13 and 16 do not rest upon brick work, they are supported on iron girders-as shown at 50. Small circular openings 51 and .52 are provided, in which pyrometers may be placed to determine the heat "in various portions of each section of the kiln, and draft gage openlugs 61 are located in the vertical ducts 18,

ir ;which a draft gage may be inserted to determine the draft. Regulating dampers 54 and 55 are placed in the vertical ducts 18 to regulate the circulation and supply of air. Y

The operation of my device is more fully described as follows :-The section of Z having been loaded with raw material brick work 29 having been replaced and heathaving been applied,

material is sufiiciently dried, fires'are then lighted upon the grate bars 27. The prodbeing as will be later shown, until the;

the bag walls 46 is forced upward-"into the crown of the arch 24, and is drawn down 42, 43 and 44, up through the vertical ducts 18 out of the branches 17 into the horizontal tubes 13, the dampers 19 of this section being open and the dampers 21 of this section be .ing' closed, se that no air can passinto the not ofthis heat; passing backward against continuous .tube"16.- The dampers 55 are also closed so that no air can enter the tops of the ducts .18.; The-dampers 22 are open and the dampers-19 are closed from the burning sections to the main cross pipe 11; (but dampers 22 are closed back of sections from whichheat is being drawn). The fan 101: draws the hot air and products of combus.

tion from thismain cross pipell and de: livers it into the cross pipe 14. from-which. it passes to thecontinuoustubes 16 and back.

to the dampers 23 which are-closed,the-same':

being at the, pointin the continuous tubes at the end of the-section;,X.1 {The dampers. 21. m the tubes 20-i-o f section?-Y- are'open.

other 'dampersm2l "are closed" from cross pipe-=14; and thedampers 19 in-the branches 17 are' closed, and the dampers55 in the .top

air gpasses downward through the. .vertical it is distributed through another mass of raw brick which is now beingjdried and heated. The dampers 41 in the-risers 39 between Y and Z are closed at this 'time. These heat produetsthen pass through the passage ways 33 into that portion. of. the

ducts 30 situated in section :Y, there being no fire in this; section, and-the fire boxes or arch ways 26 beingtempora-rily'closed,

the circulation asses downward from this portion of the nets 30,.da1iipers 32' being ducts 34, which are under section X, then into thep'assages .42, 43 and 44 through the 1 closed, past the baflie plates 37 into the lower t grilled works 45 and into the product 'drymg :m this section, from which it isdrawn through the branches 33 -into. the ducts 30- openings 31, from-which it can be drawn to: the" other sections,of-.the kiln" and passed situated in section an .then. through the through'themwiththe same obj eptj of drying and heating the'products as above described, 1

This is continued from section to section until every unit of heat has beentaken from.- the a1 r circulated or until youhave' passed the air mto the lastsection of the kiln in which the product is placed; when ,baflle plates corresponding-to 37 and 41 in. risers corresponding to 35 and 39 are closed just ahead of this section and air is drawn down I through the. openings in; the bag walls46 through the fire-box openings or arches 26 where the "portable goose-necks 49 one of.

which is shown in Fig. 8, are placed between the openings 47 and the arch ways 26, allowing the suctionfan 9 to exhaust the air, which has become cooled and moist from contact=with the products, by means of the tunnels 5, 6 and 7 to which the fan 9 is con nected by the cross tunnel 8.

, It is evident that the regulating damper 55 can be used at any time to inject fresh air,

1o when required, and the damper 54 can be opened or closed to regulate the flow through the various parts of the kiln as required by the readings of the temperature as indicated on the pyrometers which are inserted through the various openings'51 and and down through the hot brick and through the grilles 45, then through passages 42, 43 and 44 into the vertical ducts 18, out ofthe branches 17 into the horizontal tubes 13, the dampers 19 of this section being open and the dampers 21 and 55 being closed; where the heat unites with the heat from the burning section and is conducted as previously described. When the product has become cooled, the dampers 22' just ahead of this section are closed. If for any reason desired, the dampers 19, 21, 32 and 41 can be closed and the dampers 54 and 55 opened and each section of the kiln can be 'burned by natural draft, the same as anydown 4 draft If for any reason it'is necessary to cut out one section of the ln'ln, as' for example, for repairs, while the kiln is in operation, the cut-off dampers 32 may be opened and the dampers or bafile-plates cor-- .45 responding to 37 and 41 in the risers corresponding-to 35 and 39 closed, and by temporarily closing openings 33 by building in the same, hot air is drawn past the section which is out of commission, and onto the next section in regular manner; and it would not be necessary to close downthe continuous operations of the kiln.
